Add ability to delete assets to trash instead of immediate

[WilliamIsted]

• Add setting for "Move to trash before deleting".
• Add check for trash setting to deletion event.
• Add $event->sender->keepFileOnDelete = true; if trash is enabled.
• Add notice about garbage collection. Include reference to softdeleteduration.
• Add label to show how long assets will be kept for by general config. e.g. Trash will be automatically emptied after 30 days.
